One of the first articles with PhysX performance comparison, includes wide range of NVIDIA GPUs tested. At the same time, scene, choosen for benchmark, is too simplistic and does not fully represent load during actual gameplay.

There seems to be a lot of debate going on about the CPU limitation of performance in BL2. People with extreme SLI configs and/or PhysX-dedicated GPUs are experiencing poor scaling and frequent framerate drops, particularly when PhysX effects are NOT set to Low. All in all, it seems while BL2 may be great to showcase modern PhysX effects with playable framerates on the average mainstream PC, it actually sucks when it comes to PhysX gaming-oriented rigs that *should* take full advantage of hardware acceleration. The chart from 1percentgaming.com above suggests that something prevents additional GPU acceleration from really making any difference. I’d love to read PhysxInfo’s take on this issue…

funny though i have a titan with a 660 superclocked a physx gpu (medium phyx setting) and i get massive frame drops in combat many time dropping to 30 fps from a normal 60 fps while not in combat turn physx to lowa and i get constance 60 fps in combat so you tell me what is causing the drop in frame rates

Funny, indeed.
* What combination of GPU – PSS drivers are you using?
* How the game performs if you disable 660 and let Tital do all the graphics and physics work?
* How often does such slowdowns happen ? Like, every single fight, or particular one?

outWell i need to tell u smthing is definitely wrong with BL2 phsx… because even after turning off phsx on my system i was getting fps and GPU load drops …and a lot of times randomly …no idea why… tried diff methods on internet and gearbox site… then i made a clean install of graphics driver and didnt configure phsx in nvidia control panel.. Voila the 60 and above FPSes were back even in combat situations and every setting was same as it was back during pre clean install of graphic driver… then i again went to nvidia control panel.. configured phsx to once GPU and once to CPU .. in both cases GPU load and framerates were decreasing dramatically… i uninstalled phsx software .. it was still there… then i changed phsx option to CPU (despite phsx software uninstalled this option was still there) and voila.. FPSes are back to 60s…. this was an entirely hit and run method and i deduced that the way BL2 is communicating with phsx software and driver is flawed,,, games should not communicate with phsx software at all…. and yeah,, after changing to CPU the phsx option is greyed

Gearbox has acknowledged there is a problem with BL2 PhysX, there really is no need for the whole “support staff” routine. It’s not about drivers or rig set ups in general, it’s a problem in the PhysX library they are using.

Set your PhysX on high, and you will run into fps drops. It happens a lot in places with considerable height differences, liquids or if you use explosives a lot.

PhysX in BL2 clogs up the first core of the cpu even if you force the game to use the GPU for PhysX.

Hopefully they will fix it for Pre-Sequel and maybe then it can be patched into BL2 too.

I am going to build a rig with 48gb ddr3 ecc and dual 1366 xeon x5675@3.06 ghz with a radeon 290x. So i am going to make a full testing on bl2 and pre-sequel. Also raid 0 ssd on sata-2 controller 2×250gb samsung 850 evo And pci express 2.0(8gb/s).

I made a preview on hp dl380 g6 server with 80gb ddr3 dual x5675 and raid 0 ssd on Sata2 controller. Ati 5870 at 8x on pci express 1.1 (very low data transfer 2gb/s) and got impressive results. At fullhd all settings at max and 70-80 fps average with physx at max (editing the ini file and forcing physx).

I do not own a 2k nor 4k monitor to test, but 1080. So i will update my results as soon as the new board is delivered and the setup complete. Stay tuned xD
